As of right now, PCMag has written 68 stories about the products, trends, and services on display at Mobile World Congress 2012 in Barcelona. The vast majority of those were done by Chloe Albanesius and Sascha Segan, who have been working the floor for the last week. Asus Tablets, 41MP Camera phones, and a handset that runs on an Intel CPU? If you missed anything this week, Sasha's wrap up is a nice primer.

There is no doubt that this week was all about the phones, but that didn't stop Microsoft from going public with a free preview of Windows 8. We have been playing with the Developer Release for a few months now, but now you can download the OS and see how far Microsoft has come. To really get the most out of the new Metro interface you should install it on a tablet so you can take advantage of the touch experience. If you find that daunting, check out Michael Muchmore's excellent and detailed hands on.

Of course, at least for now, most Windows 8 downloaders will be running it on desktops. How exactly will Metro's touch-centric interface work with a traditional mouse and keyboard? ExtremeTech's Sebastian Anthony loaded it on a multi-monitor desktop and took it for a spin. It is too early to judge OS performance, but he clearly hit a few hitches. Just try to count how many clicks it takes to shut down the PC.

A flood of ultrabooks is about to hit the market, and Dell is doing what I hoped it would—building a system that is designed to compete on design, not just on specs. The XPS 13 is a beautiful system with a slick carbon-fiber frame that would impress the most avid Apple fan. The fact it has no VGA, Ethernet, or HDMI should give travelers that need to connect to external monitors pause, but deficiencies like that haven't exactly hurt the MacBook Air's sales. This ultrabook is worth a closer look. Check out our full review.

After months of speculation, we will finally get some details on the iPad 3 next week. The rumors have been so exhausting to follow—7-inches, Retina displays, LTE—it seems like it will be a tough crowd to impress next week. Geek.com has come up with some possible announcements that could still manage to surprise the tech press. Gotta say, I think turning the iPad into a serious gaming platform isn’t surprising. I'd put money on it.
